both remote system water temperature and boiler
modulation rate. For example, the lead boiler can be
configured to start a lag boiler after operating above
90% modulation rate for longer than an adjustable
time. The boilers are modulated in "unison"
(parallel) modulation rate to ensure even heat
distribution.
